The FBI raided a clinic in Green Tree Wednesday afternoon.
Agents were seen carrying boxes from Highfield Urgent Care along Green Tree Road.
An FBI spokesperson confirms they were "conducting law enforcement activity" there, but did not provide any additional detail.
One patient said he was turned away when he showed up for his appointment Wednesday.
"I was here to get an MRI done. I walked into the building and got through the first door and met an FBI agent. She proceeded to tell me that I won't be able to get the MRI done today because they were executing a federal search warrant," he said.
A building owner across the street told News Radio KDKA the clinic has been swamped for the last two years, and was a popular place for COVID-19 testing.
